How do you multiply #1/2 (2n - 4) - 2n#?

Answer 1

-n-2

I'm not sure if you intended to "simplify" because there isn't much multiplication in this string.

use order of operations here by multiplying #(2n - 4)# by #1/2# which gives you #((2n)/2 - 4/2)#. when you do the division, you are left with #n - 2#. remove the brackets and group like terms:

#n - 2 - 2n# #x = -n - 2#

To multiply ( \frac{1}{2} (2n - 4) - 2n ), first distribute ( \frac{1}{2} ) to ( 2n - 4 ) and then subtract ( 2n ).

[ \frac{1}{2} (2n - 4) - 2n = \frac{1}{2} \cdot 2n - \frac{1}{2} \cdot 4 - 2n = n - 2 - 2n ]

Next, combine like terms:

[ n - 2 - 2n = (1 - 2)n - 2 = -n - 2 ]

So, ( \frac{1}{2} (2n - 4) - 2n = -n - 2 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
